BIOS Beep Codes - Error Codes

Finally after some long search i've found this information.

BIOS Beep Codes

Have you ever found your computer cannot be turned on? The power light is on but there's nothing happen but some beeping sounds. Then you got to know this information.

When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.

Computer 101 : Why PC crash? Part 2 : Bad Ram

We have talk about Hardware Conflict in Computer 101 : Why PC crash? Part 1 : Hardware Conflict
Now we're gonna talk about another reason why PC crash

Part 2 : Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

Computer 101 : Why PC crash? Part 1 : Hardware Conflict

Have you ever found your PC suddenly stop running? or got the notorious blue screen of death? or even restarting by itself ? If you haven't, consider yourself very lucky :D

I'm gonna share to you about reasons why you get those very annoying and depressing momment

What can you do? More importantly, how can you prevent it happening?

Part 1 : Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device. For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen.

The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is http://www.driverguide.com/. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Microsoft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

23 Ways To Speed Up Windows XP

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system.

If you're not sure, here's how to check:
First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key.

This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

Here's how:
First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup.

Here's how:
Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility.

Here's how:
First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip:
open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.

Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Registry Cleaner >> Boost Operating Speed - Repair ActiveX, DLL, Runtime Errors - Stop System Crashes

Do you feel your PC's slowing down? or even stop running and crash? >_< , dont think to reinstall your OS yet, maybe you just need to clean your windows registry

A Registry Cleaner is a specialized software tool used to safely clean out and repair the Windows Registry. The Windows Registry is a database which stores configuration settings for all hardware, selected system options, memory setup and software installed on your computer. This includes user preferences, settings and licence information.

Manually editing the registry is extremely dangerous for your computer's operating system. It reaaaaally not recommended for n00b (like me). However, problems can also occur if the registry is not regularly maintained. If you don't fix registry problems as they arise or don't try to prevent them from occurring at all, then your computer system may begin experiencing system crashes, stalls or slower operating speeds. If you place high importance on fixing registry problems and preventing system crashes you'll end up with greatly improved system stability and operating speeds.

The Windows Add/Remove Programs utility and even official software uninstallers do not thoroughly clean your registry entries. A registry cleaner is a tool that allows you to get rid of troublesome and obsolete registry entries created by software and drivers that were not properly uninstalled in the past. It does not require any technical expertise to use it so don't be concerned about any limitation in computing knowledge.

As well as fixing registry problems, an even bigger advantage of having a good quality registry cleaning tool is that it can prevent problems from occurring in the first place. It will help you to repair and prevent many types of computer errors including ActiveX, DLL and runtime errors. Regardless of how old your computer system is or how it's used, there are many good reasons for cleaning an error-prone registry.

Some good reasons to clean your registry:

• you frequently install and uninstall programs
• you uninstalled programs that were never completely uninstalled
• you have Spyware or Adware programs that you can't uninstall
• you have uninstalled hardware
• you have unused drivers on your system

With so many changes occurring over time through the normal use of your computer, your registry can become filled with errors and obsolete entries. Whenever you remove programs, it's highly probable that not all the components are completely removed from your hard drive or registry. If your registry is not properly cleaned of these obsolete entries and errors you'll be left with ongoing system problems as your computer attempts to process invalid instructions.

I'm not suggesting a specific registry cleaner here, just search by google, you'll find plenty of them. If you're too lazy to do that (sigh) this the search result for you

A good quality registry cleaner should also be able to detect:

• Missing startup programs
• Missing file associations
• Invalid application paths
• Invalid device drivers
• Missing help files
• Missing DLL files
• Missing system fonts

System Restore, my saviour^^

Yesterday i just got bad experience with my virus scanner, i downloaded the update and have it installed on my pc, just like i did every weeks before. But that day was special, after the update proccess finished, the antivirus stop running. First, i dont realize it yet tho, i just about to watch a movie with windows media player and got "internal error occured" message. What on earth has happened?

Ok, dont panic yet, i try to restart my pc. Strange... the shutdown proccess looked a little bit different -_-a. After booting proccess completed, i just found i cant get in to windows again. I always got error message in login screen. After several attempt, i gave up :( .

I restart my pc again and login to safe mode. And without any hesitation, i restore my pc to several weeks before :( . After few minutes of waiting... taadaaa, my windows is back and running : ) Many of my installed programs has gone, but that's ok.

So guys, maybe this's look like simple and easy to forget, but system restore can be very helpfull in such a critical time like that. Just remember to create a restore point every week : )

How to create a restore point :

• Click system restore from start windows > program > accessories > system tools
• There'll be a choice, to create a restore point or restore computer to a restore point
• Choose create a restore point
• Put a description the click OK, done

How to restore your computer :

• Click system restore from start windows > program > accessories > system tools
• Choose restore computer to a restore point
• Choose the restore point that you have created or outomatically created by windows after you install someting
• Windows will restart and done

5 ways to speed up your PC

By following a few simple guidelines, you can maintain your computer and keep it running smoothly. This article discusses how to use the tools available in Windows XP Service Pack 2 (SP2) and Windows Vista to more efficiently maintain your computer and safeguard your privacy when you're online.

Free up disk space

By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.Use Disk Cleanup to:

•Remove temporary Internet files.
•Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
•Empty the Recycle Bin.
•Remove Windows temporary files.
•Remove optional Windows components that you don't use.
•Remove installed programs that you no longer use.

Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.

To use Disk Cleanup

1.Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.


2.In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
Choose the files that you want to delete.


3.Clear the check boxes for files that you don't want to delete, and then click OK.

4.When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.

Speed up access to data

Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.

Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.

When to run Disk Defragmenter

In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:

•You add a large number of files.
•Your free disk space totals 15 percent or less.
•You install new programs or a new version of Windows.

To use Disk Defragmenter:

1.Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.

Click Analyze to start the Disk Defragmenter.


2.In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.

Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.

3.To defragment the selected drive or drives, click the Defragment button. Note: In Windows Vista, there is no graphical user interface to demonstrate the progress—but your hard drive is still being defragmented.
After the defragmentation is complete, Disk Defragmenter displays the results.

4.To display detailed information about the defragmented disk or partition, click View Report.

5.To close the View Report dialog box, click Close.

6.To close the Disk Defragmenter utility, click the Close button on the title bar of the window.

Detect and repair disk errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.

If you use your computer daily, you should run this utility once a week to help prevent data loss.

To run the Error Checking utility:

1.Close all open files.

2.Click Start, and then click My Computer.

3.In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.

4.In the Properties dialog box, click the Tools tab.

5.Click the Check Now button.

6.In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.


7.If bad sectors are found, choose to fix them.

Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.

Protect your computer against spyware

Spyware collects personal information without letting you know and without asking for permission. From the Web sites you visit to usernames and passwords, spyware can put you and your confidential information at risk. In addition to privacy concerns, spyware can hamper your computer's performance. To combat spyware, you might want to consider using Microsoft Windows Defender, which is included in Windows Vista, and is available as a free download for Microsoft XP SP2. Alternatively, there are other free anti-spyware software programs available.

Learn all about ReadyBoost

If you're using Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory. Learn more.

Guide for Fixing Computer Game Problems

New Game Blues

If you have bought a new game recently, and popped it in to your computer expecting gaming bliss, only to find that it crashes or locks up your whole system, then this article is for you.

Step One - Get Some Help

Maybe the game manufacturer has already updated the game and you no longer have a problem. So, the first thing you should do is visit the game manufacturer's web site and determine if there is a "game patch" to download. Also, visit the manufacturer's support area and see if there is a FAQ (frequently asked questions) or other tips that might help you.

Another good resource is game "fan" sites. For almost all recent games, third parties have developed web sites with a host of information on the new game. These sites can be found through the game manufacturer's site links or by searching on the name of the game. Many of these sites have bulletin or discussion boards, and most will have an area dedicated to game problems. Don't be shy about posting your problem if no one else has posted it.

Step Two - Identifying the Problem

So how does one go about coaxing a new game to run? Do you promise to make amends for past deeds if only the game will work? Maybe you could wiggle some cables or something? Or should you just give up and run down to the computer store and buy a new computer, motherboard, or video card?

The first thing you should know is, "If your computer worked fine before loading the new game, then the game is the cause of the problem, not the computer". Provided that your computer meets the manufacturer's minimum specifications (available on the game box) for running the game, you should not have to buy any new hardware.

So instead of pulling your hair out, apply the steps below in the order listed. After each step, you should try to run your game to see if the problem is corrected.

Warning - While you may choose to perform all steps, you should be aware that the steps progressively become riskier and could cause your computer to become unstable or unbootable if not performed correctly.

Step Three - Update and Test DirectX Drivers

Microsoft's DirectX is required to run most new and old games. It can be obtained free from Microsoft's Windows Update Page. The majority of games will include a version of DirectX on the game's CD-ROM. If the new game is well behaved it will ask if you want to load its version of DirectX.

[Warning - If you have a newer version of DirectX already on your system - don't load an older version. This could corrupt current, or install older, drivers. Most games will usually work fine with a newer version of DirectX than the game requires.]

OK. Good Advice. So how do you know what version of DirectX you have? Use your file manager to open the DirectX directory and click on a program called DXDIAG.EXE. Use search if you dont know where the file is.

This will open the DirectX Diagnostic Tool which not only reports the version of DirectX you have loaded (on the bottom of the first tab), it also lets you test your video and audio systems for conflicts. You should definitely click on all of the tabs and perform all the tests to make sure there are no problems.

Step Four - Obtain the Latest Video and Sound Drivers

You have a required, or newer version, of DirectX and the DirectX Diagnostic Tool doesn't report any problems, but you game is still crashing. Now what?

The next step is to obtain the latest video and sound drivers. While DirectX/Windows does have some drivers included, you should visit your audio and video card manufacturers' web sites to look for updated drivers. These are usually available in the technical support section of the site and can be downloaded free.

Another possibility for video drivers is to visit the graphic chip manufacturer's site (which you should only do if your graphic card manufacture is doing a poor job of releasing new drivers), e.g. if you have a NVidia GeForce card you could visit NVidia's web site.

Step Five - Adjust BIOS Settings

You loaded the latest video and sound drivers and the game still doesn't work - time to check those BIOS settings.

On most desktops, the BIOS settings screen is activated by pressing the Delete key during the startup boot check of system RAM. Once you are in the BIOS you can try changing the following items, one at a time, to see if they enable your game to work. Your BIOS probably has various sections and you will have to locate these attributes to change them. No changes will be made in the BIOS unless they are saved before you exit. So if you make BIOS changes, but then decide you really don't want to save them, don't save the changes when you exit.

Warning - The following changes could keep your computer from operating properly. Before changing an item, write down your original setting. Do not change any settings other than those described. Your BIOS may or may not have the following items.

Recommended Settings

1. Enable "Assign IRQ to VGA" .
2. Disable "VGA Palette Snoop".
3. Disable "Video Bios Shadow" and video memory address shadowing like "C800-CBFFF".
4. "AGP Aperture" size should be one-half of available system RAM.
5. Reduce "AGP Speed" to 2/3 (especially good for overclockers).
6. Un-overclock your CPU (of course this is a last resort).

Last ResortsIf nothing else has worked, than the solutions listed below are the last things you should try. You should probably seek help again from your manufacture and other users before you try these ideas.

Warning - These solutions could definitely keep your system from operating properly and should not be undertaken by novices.

1. Move your PCI video card into a different slot. Some PCI video cards will pick up interference from the cards next to them. Trying a different slot might help.
2. Flash your video card's BIOS. New video cards have a flashable BIOS just like a motherboard's. If there is an update to your BIOS it will be available at your video card manufacturer's web site.
3. Flash your motherboard's BIOS. Any BIOS upgrades will be available at your motherboard manufacturer's web site.

That's it i guess. Well, if you have any critics or idea please make a comment here
